Remarks

The PPOP class implements a standard internet post office (POP3) client, as specified in RFC 1725, and supports decrypting and verifying signatures of encrypted and signed emails using OpenPGP. You can send an OpenPGP signed and encrypted message using the PSMTP class by calling the Encrypt, Sign, and SignAndEncrypt methods.

Connect to the Server

To connect to a MailServer, first set the appropriate User and Password and then connect by calling the Connect method. Upon successful connection to the MailServer, the number of waiting messages is shown by the MessageCount property. A message is selected by setting the MessageNumber property to a number between 1 and MessageCount (inclusive). Then, the message text and/or headers are received by calling the Retrieve method.

Receive Messages

The message text is received through the Transfer event, whereas the message headers are received through the Header event. Additionally, up to MaxLines from the message body are provided in the MessageText property. The StartTransfer and EndTransfer events are fired at the beginning and end of message transmission. The PITrail event provides a trace of the interaction between the client and server (excluding message transfers).

Verify

To verify the signature of a message specify the public key to be used for signature verification by setting the SignerKey* properties. For instance: PPOP1.SignerKeyCount = 1 PPOP1.SignerKeyKeyring(0) = "c:\my_keyring_dir" PPOP1.SignerKeyUserId(0) = "sender@nsoftware.com" The specified public key will be used to verify the signature when calling VerifySignature.

Decrypt

To process an encrypted or signed message first retrieve the message text and headers by calling Retrieve. To decrypt a message specify the private key to be used for decryption by setting the Key* properties. For instance: PPOP1.KeyCount = 1 PPOP1.KeyKeyring(0) = "c:\my_keyring_dir" PPOP1.KeyUserId(0) = "recipient@nsoftware.com" PPOP1.KeyPassphrase(0) = "password" The specified private key will be used to decrypt the message when calling Decrypt.

Decrypt and Verify

To decrypt and verify in one step, you can call DecryptAndVerifySignature. Set the public key of the sender in the and the private key to be used for decryption in the Key* properties .

Remarks

The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the Keyring. When this property is set the class will search the Keyring for a key associated with the UserId specified.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and KeyOtherUserIds after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The class will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP class's RecipientInfo event.

The $keyindex parameter specifies the index of the item in the array. The size of the array is controlled by the KeyCount property.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and KeyOtherUserIds after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The class will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP class's RecipientInfo event.

The $signerkeyindex parameter specifies the index of the item in the array. The size of the array is controlled by the SignerKeyCount property.

ipworksopenpgp_ppop_set($res, 161, $value );

Default Value

''

Remarks

This property contains the user identifier for the mailbox. This property must be set before the class connects to the MailServer.

Data Type

String

Config Method (IPWorksOpenPGP_PPOP Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksopenpgp_ppop_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Connect Method (IPWorksOpenPGP_PPOP Class)

This method connects to the mail server and attempts to log in.

Object Oriented Interface

public function doConnect();

Procedural Interface

ipworksopenpgp_ppop_do_connect($res);

Remarks

This method connects to the mail server and attempts to log in using the current User and Password. Then it retrieves the initial statistics about the mailbox contents (MessageCount and QueryTotalSize).

Example. Connect to POP Mailbox:

POPControl.MailServer = "MyPOPServer" POPControl.User = "username" POPControl.Password = "password" POPControl.Connect() POPControl.MessageNumber = 1 POPControl.Retrieve() MessageText = POPControl.MessageText MessageHeaders = POPControl.MessageHeaders

Decrypt Method (IPWorksOpenPGP_PPOP Class)

Decrypts the message.

Object Oriented Interface

public function doDecrypt();

Procedural Interface

ipworksopenpgp_ppop_do_decrypt($res);

Remarks

This method decrypts the specified message.

The message will be decrypted using the keys specified in Keys. Before decryption begins the class will fire the RecipientInfo event with information about the encrypted message, including the key used to encrypt the message. Within this event you may use the available information to load the correct key into Keys.

DecryptAndVerifySignature Method (IPWorksOpenPGP_PPOP Class)

Decrypts and verifies the signature of the message.

Object Oriented Interface

public function doDecryptAndVerifySignature();

Procedural Interface

ipworksopenpgp_ppop_do_decryptandverifysignature($res);

Remarks

This method attempts to both decrypt and verify the signature of the message. All of the properties affected by calling the Decrypt and VerifySignature methods are affected in the same manner.

This method may be used when the data is signed, encrypted, or signed and encrypted. For instance, if the data is encrypted but not signed you may still use this method and the class will perform the decryption without error.

The message will be decrypted using the keys specified in Keys. Before decryption begins the class will fire the RecipientInfo event with information about the encrypted message, including the key used to encrypt the message. Within this event you may use the available information to load the correct key into Keys.

The message will be verified using the keys specified in SignerKeys. Before verification begins the class will fire the SignatureInfo event with information about the signature including the key used to sign the message. Within this event you may use the information available to load the correct key into SignerKeys.

By default, if the signature is not valid the class fails with an error. The configuration setting RequireValidSignature may be set to False to disable this requirement. When RequireValidSignature is set to False, the Status parameter of the VerificationStatus event should be checked to determine the result of the operation.

NOTE: This method does not attempt to check the validity of the signing key itself.

Delete Method (IPWorksOpenPGP_PPOP Class)

This method deletes a message specified by MessageNumber on the server.

Object Oriented Interface

public function doDelete();

Procedural Interface

ipworksopenpgp_ppop_do_delete($res);

Disconnect Method (IPWorksOpenPGP_PPOP Class)

This method disconnects from the mail server.

Object Oriented Interface

public function doDisconnect();

Procedural Interface

ipworksopenpgp_ppop_do_disconnect($res);

Remarks

Remarks

This event fires when the passphrase for the key is required. The passphrase must be specified before operations requiring the secret key are attempted. The passphrase may be supplied by setting the Passphrase parameter in this event, or by specifying the KeyPassphrase property before attempting the operation.

The passphrase is required when using the following methods in KeyMgr:

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

When using the OpenPGP class, or an email-based class, the following methods require a passphrase for the key:

• Decrypt
• Sign
• SignAndEncrypt

UserId holds the user Id of the key the passphrase is required for.

The UserId format is:

FirstName LastName (Comment) <Email>

Note that for OpenPGP v6, a key may be created with or without a UserId, as the field is optional. If a key was created without a UserId, the key's Fingerprint can be used as it's identifier instead.

KeyId is the hex-encoded, 4-byte or 8-byte Id of the key the passphrase is required for. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key the passphrase is required for. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

Parameter List

 'keyid'
 'fingerprint'
 'publickeyalgorithm'

Remarks

This event fires when the Decrypt or DecryptAndVerifySignature method is called.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to encrypt the message. If a subkey was used to encrypt the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

The KeyId and Fingerprint parameters can be used to identify the correct key to specify in the Key* properties. The Key* properties can be set from within this event as this event fires directly before the decryption process begins.

It is recommended to use the Fingerprint to identify the correct key, as it is possible for different keys to have the same KeyId.

PublicKeyAlgorithm is the algorithm of the public key used to encrypt the message. Possible values are:

• RSA
• DSA
• ECDSA
• EdDSA
• Ed25519
• Ed448
• RSA-Legacy
• ECDH (Subkeys only)
• X25519 (Subkeys only)

SignatureInfo Event (IPWorksOpenPGP_PPOP Class)

Fired during verification of the signed message.

Object Oriented Interface

public function fireSignatureInfo($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 10, array($this, 'fireSignatureInfo'));

Parameter List

 'keyid'
 'fingerprint'
 'signingalgorithm'
 'publickeyalgorithm'

Remarks

This event fires when the VerifySignature or DecryptAndVerifySignature method is called. It provides information about the signature of the message.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. If a subkey was used to sign the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

The KeyId and Fingerprint parameters can be used to identify the correct key to specify in the SignerKey* properties. The SignerKey* properties can be set from within this event as this event fires directly before the verification process begins.

It is recommended to use the Fingerprint to identify the correct key, as it is possible for different keys to have the same KeyId.

SigningAlgorithm describes the hash algorithm used when the message was originally signed. This value is applicable only to the message signature, not the key used to sign the message. Possible values are:

• SHA1
• MD5
• SHA256
• SHA384
• SHA512
• SHA224
• RIPEMD160
• SHA3-256
• SHA3-512

ipworksopenpgp_ppop_register_callback($res, 11, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
 'certsubject'
 'certissuer'
 'status'
 'accept'

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (IPWorksOpenPGP_PPOP Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 12, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (IPWorksOpenPGP_PPOP Class)

This event is fired when the message starts transferring.

Object Oriented Interface

public function fireStartTransfer($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 13, array($this, 'fireStartTransfer'));

Parameter List

 'direction'

Remarks

The StartTransfer event is fired when the message body starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Status Event (IPWorksOpenPGP_PPOP Class)

Shows the progress of the operation.

Object Oriented Interface

public function fireStatus($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 14, array($this, 'fireStatus'));

Parameter List

 'message'

Remarks

The event is fired for informational and logging purposes only. It may be used to track the progress of an operation.

The level of detail is controlled by the LogLevel setting.

Transfer Event (IPWorksOpenPGP_PPOP Class)

This event is fired when the message is transferred from MailServer .

Object Oriented Interface

public function fireTransfer($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 15, array($this, 'fireTransfer'));

Parameter List

 'direction'
 'bytestransferred'
 'percentdone'
 'text'
 'eol'

Remarks

The Text parameter contains the portion of the message data to be retrieved.

The BytesTransferred parameter contains the number of bytes transferred since the beginning of the message, including header bytes. At the end of transmission (i.e., when the last Transfer event is fired), BytesTransferred equals the value of the QueryMessageSize method.

The Transfer event is fired for every line of the message. For complete lines, there is no terminating newline at the end of the Text parameter, and EOL is True. The EOL parameter is False when a line is broken (usually for being too long).

A faster way to retrieve a message is to assign a value to the LocalFile property and use the Transfer event to check the progress rather than to get the actual data.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Note: For the PercentDone parameter value to be correct, the GetMessageSize configuration setting must be set to True.

VerificationStatus Event (IPWorksOpenPGP_PPOP Class)

Fired after verification of the signed message.

Object Oriented Interface

public function fireVerificationStatus($param);

Procedural Interface

ipworksopenpgp_ppop_register_callback($res, 16, array($this, 'fireVerificationStatus'));

Parameter List

 'keyid'
 'fingerprint'
 'status'

Remarks

This event fires when VerifySignature or DecryptAndVerifySignature is called. It provides information about the result.

KeyId is the hex-encoded 4- or 8-byte Id of the key used to sign the message. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's Fingerprint. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's Fingerprint instead. For instance:

5E70662EA810E768

Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

Status holds the result of the operation. Possible values are:
